Vampires are definitely the hot ticket at the moment, In recent months we have seen the very successful launch of True Blood on HBO derived from the Charlaine Harris Sookie Stackhouse books, and the Twilight movie from Stephenie Meyer this past weekend did huge numbers despite lukewarm reviews and also an option on the Anita Blake Vampire Hunter stories from Laurell K. Hamilton.
Now the popular "House of Night" YA novels by P.C. Cast and daughter Kristen Cast have been optioned. Read the announcement released at Variety last week. To date there have been four books in the series. Book 5 - Hunted is due for release March 2009.
